A Guy Is Hoping to Set a World Record Running in 130-Degree Heat Wearing a Darth Vader Costume [VIDEO]

If you think it's hot out, try this: every year in Death Valley, California, there's something called the Badwater Ultramarathon where a bunch of crazy people run 135 miles in temperatures that top 120 degrees.

It's an extreme sport called "heat running." But apparently running in extreme heat gets boring after a while, so a guy named Jonathan Rice added a new element.

For the past few years, he's been going to Death Valley and running one-mile sprints in a full Darth Vader costume.

He calls it the "Darth Valley Challenge" and it's actually becoming popular. Now other runners are showing up dressed as "Star Wars" characters including Princess Leia, R2-D2, Chewbacca, and Yoda.

This year, Rice did it in 129-degree heat and clocked in at six minutes, thirty-six seconds. That's about 20 seconds shy of his personal record. But he was specifically trying to set a world record for the "hottest verified run."

The official temperature when he started his run was 129 degrees. He's still waiting to hear back from Guinness.
